$q$-expansion

The dimension is sufficiently large that we do not compute an algebraic \(q\)-expansion, but we have computed the trace expansion.

\(\operatorname{Tr}(f)(q) = \) \( 24 q - 20 q^{7}+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 24 q - 20 q^{7} + 20 q^{13} - 40 q^{19} + 6 q^{25} + 4 q^{31} - 2 q^{37} - 24 q^{43} + 2 q^{49} + 36 q^{61} + 20 q^{67} + 12 q^{73} - 16 q^{91} - 30 q^{97}+O(q^{100}) \) Copy content Toggle raw display
